From energy-generating toilets to poop-powered vehicles, there’s a wealth of innovative eco-friendly projects out there that transform human waste into a valuable resource. Read on for a look at some of our favorite poop-a-rific green projects!
Many developing countries do not have toilets or even proper sewage disposal systems, which can lead to the spread of bacteria and water-born illnesses. With these issues in mind, designer Virginia Gardiner created a solution to both problems, called the LooWatt. The eco-commode is itself made from poop – it has been molded from 90% horse dung, with a biodegradable lining. Aside from creating a sanitary place to sit and think, when the LooWatt is full, the waste can be turned into energy with the aid of a biodigestor, bringing sanitation and an energy source to underdeveloped countries.
Poop fuel, poop toilets, poop bricks – how about poop meat? Scientist Mitsuyuki Ikeda at the Environmental Assessment Center in Okayama has developed what has been nicknamed the “poop burger.” Created by extracting protein and lipids from “sewage mud” (human poop), the elements are whipped into “meat” in an exploder, then mixed with savory ingredients like soya and steak sauce. Meat eaters and vegetarians alike may recoil, but the faux meat was created with the goal of reducing carbon emissions in mind, as the meatpacking industry contributes 18% of greenhouse gas worldwide.
